Title: Manufactor of iron core
Inventor: KARIYA TERUO
IPC: H02K15/02
Filed: 1981-02-05
Abstract: PURPOSE:To radially form a coil slot by punching in a correct radial direction by varying the relative position between the center of the axis of an iron core winding drum and the slot punching point on a line which connects them. CONSTITUTION:A strip magnetic plate punched with slots at slot punching points P is wound on a winding drum 6. When the outer diameter of an iron core 5 is increased in the winding step, a level 13 is rotated in a direction of an arrow Y3. When a switch F is then closed, a motor 17 is driven to move the center Q of the drum 6 in a direction of an arrow Y4. Thus, the lever 13 is moved on the basis of the recoiling force of a spring 14 in a direction of an arrow Y2. The switch F is again opened, and the center Q of the drum 6 is stopped from moving. In this manner, the line which connects the punching point P and the winding points O0, O1 of the core can be always maintained in the prescribed direction. Therefore, the coil slot can be correctly radially formed.

Title: Casing for inflatable air bag in automobile
Inventor: WAGENER KEIT
IPC: B60R21/20
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent expansion of a projection path in an inflation process of an air bag by providing a reinforcing rib, which prevents expansion of the projection path, on the outline face in a multifunction casing provided with integrated multiple wall structure. SOLUTION: In multiple wall structure, it is very effective when two or more parallel chamber hollow parts 5.1, 5.2, which are separated from each other, form an outside wall 5 in the form of a sandwich structure for a front chamber 4. In the outside wall, whose structure is similar to bridge structure, of the multiple wall, a lateral reinforcing rib 6 forms a supporting structure in a parallel arrangement. The casing is formed of transformed polyamide and is reinforced by means of glass fiber in addition for increasing strength. The casing rigidity can be improved when the chamber wall is constructed of a multiple wall, and when the unsupported outside face of the outside wall receiving the air bag is provided with the reinforcing rib 7 additionally. These reinforcing ribs 7 work effectively when they are spread from the weakest point in the chamber wall 5.

Title: Synchronization acquiring method
Inventor: NAKAGAWA YOSHIKATSU
IPC: H04B1/7075
Filed: 1993-01-06
Abstract: PURPOSE:To acquire initial synchronization by more stable sliding correlation by contriving offset fluctuation at the time of adding and removing offsets. CONSTITUTION:A DC bias voltage Vs is the DC bias voltage for setting a free-running frequency for supplying a chip rate at the time of synchronization tracking to a VCO and  V is a DC offset voltage for supplying a frequency offset required for the sliding correlation. A SW1 and the SW2 are switched by trigger signals at the time of starting initial synchronization acquisition, the offset voltage is added through an RC circuit constituted of a capacitor C and a resistor R to the DC bias voltage Vs and applied to the VCO. The offset voltage v(t) to be added at this time is the transient response output voltage of the RC circuit for a step-like input voltage  V. When the time when the respective switches are turned ON is defined as (t)=0, the offset voltage v(t) increases exponentially.

Title: Ink jet head
Inventor: MATSUMOTO MICHIO
IPC: B41J2/055
Filed: 1985-01-31
Abstract: PURPOSE:To increase reliability of an ink check-valve by using a ball. CONSTITUTION:A check-valve consisting of a ball 8 and a ball guide 7 is provided within an ink supply entrance 3, and if a pulse voltage is applied to a piezoelectric body 1, the capacity of an ink chamber 5 instantly decreases and uniform pressure is created within the ink chamber, pushing the ball 8 tightly against the ink supply entrance 3, and the back flow of the ink is prevented. And the ink is discharged only from a nozzle 4 where there is no resistance. When the piezoelectric body 1 restored its normal condition, a negative pressure is created within the ink chamber 5, causing the ball 8 to be released from the ink supply entrance 3 and to stop at where the ball guide 7 is provided, and the ink is supplied into the ink chamber 5. The ball guide 7 is fixed to the wall of the ink chamber 5 around the ink supply entrance 3, and is conically shaped with its top cut off and retains the ball 8 to be able to contact with and released from the supply entrance 3 without deviating from the center. Thus, the function of the back flow valve is accurate and its structure is simplified, resulting in production of a reliable product.

Filed: 1982-02-08
Abstract: PURPOSE:To increase demagnetizing effects by a method wherein a positively and  negatively inversional demagnetizing pattern is caused to act on a material to be  demagnetized repeatedly in harmony with the movement of the material being rotated and moved. CONSTITUTION:A U-shaped magnet comprising a yoke, magnetic poles 6, 7 and exciting coils 8, 8A are installed on a support 9, the magnet being in contact with the  under surface of a steel material 1. The steel material 1 is moved forwardly at low  speed by a turning roller 10. Then the steel material 1 is divided into meshes to be demagnetized equivalent to the interval lp of N, S magnetic poles 6, 7 mutually different polarity and demagnetized on a mesh basis. A demagnetizing pattern applied to  each mesh is such that it is positively and negatively inversional on a mesh basis,  whereas the exciting coils 8 and 8A are connected in series. Each coil is then wound  so that the current flowing through the exciting coils 8 and 8A are inversional. Accordingly, the magnetic pole 6 has the N polarity and the magnetic pole 7 has the S  polarity in the first half semicycle in each mesh. On the contrary, the magnetic poles  6 and 7 have the S and N polarity, respectively in the second semicycle. Thus demagnetizer makes one or two rounds of the mesh to be demagnetized to link the demagnetized zones of the steel material 1 in an annular from.
